Try subscribing to Bionet.software. This newsgroup is set up specifically for
questions such as yours (it's the most common question out there). Yes, there are
several packages available, but I can't recommend one as I haven't found one that suits
my needs yet -- I'm pretty picky ;)
Maybe we could find a few people out there that would be willing to try many of the
shareware packages available and post a review of several of them on a web page? I'd
think about it if I had a web page
